Abstract

An arrangement for ventilating a room uses the operation of the fan to open a ventilator at the same time, and close it when the fan stops. The drive spindle for the fan blades carries an arrangement of cranked arms mounting centrifugal weights, so that when the baldes and shaft rotate the weights swing out under centrifugal force. This causes a lifting of the ends of the arms attached to a collar, so that this also is lifted so as to tilt the slats of the ventilator. The moving parts can be made of any suitably rigid material. Other types of outlets or windows can be operated by suitable components by the operation of the fan.
